Kines 165 Exam 1 Questions with Answers
(100% Correct Answers)
Cardiorespiratory endurance Answer: the ability of the heart, lungs, and blood
vessels to deliver adequate amounts of O2 to working cells to meet the demand
of prolonged exercise
Prolonged sustained activities: Answer: rely mostly on aerobic energy systems
(in order to support the on- going need for ATP regeneration)
Cardiorespiratory endurance is dependent on: Answer: the ability of
cardiorespiratory system to: deliver O2 to working muscles
working muscles ability to: extract O2 and use extracted O2 to produce energy
via aerobic metabolic pathways
Is there performance carry over? can those with significant CR endurance run a
very fast mile? Answer: NO
Aerobic power (VO2 max) Answer: the maximal volume of O2 that can be
consumed during "all out" sustained aerobic exercise
best index of cardiorespiratory fitness
dictated by the athletes ability for O2 delivery and extraction
Components of aerobic power (VO2max) Answer: HR max (marker of O2
delivery)
SV max (marker of O2 delivery)
a-vO2D max (marker of O2 extraction)
,2
VO2max score provides: Answer: a quantitative expression of the maximal
capacity for aerobic ATP regeneration
VO2 max is an important factor in: Answer: determining an athletes ability to
SUSTAIN high intensity exercise
For who is a high VO2 max crucial? Answer: a miler
A high O2 capacity requires: Answer: the integrated and high level responses to
diverse physiologic support systems (cardiorespiratory, neuromuscular,
musculoskeletal, neuroendocrine)
Direct assessment of O2 power requires: Answer: 1. incremental exercise test
taken to volitional exhaustion
2. collection of expired gases
Aerobic fitness is the single most important component of health related
physical fitness Answer: best indicator of overall health
Muscular strength: Answer: ability of a muscle (or muscle group) to express
maximal force against a resistance
* most commonly tested by 1 RM technique
Muscular strength is influenced by: Answer: 1. muscle size (cross sectional
area)***
2. fiber type
3. trained state
4. neuromuscular skill (ability to maximally recruit, stimulate muscles) ** easily
learned, explains fast initial increases in strength in the early stages of training
Muscular strength biomechanics: Answer: in order for a muscle to produce
maximal force, it must receive maximal stimulation from the nervous system
, 3
Muscular power: Answer: the rate of doing work (power= work/time) the
ability to express force at high velocity (power= force x velocity)
* the quality that gives athletes ability to accelerate, move quickly
** one of the most important components of fitness in the traditional American
team sports
Muscular endurance: Answer: ability of a muscle (or muscle group) to sustain
repeated action against a submaximal LOAD
Muscular endurance imposed load may require: Answer: isometric action
(handgrip dynamometry)
dynamic (concentric/eccentric) action (pushups)
Muscular endurance assessment: Answer: 1. number of pushups and/ or sit ups
in a continuous set
2. how many reps wth a 65% bench press
Muscular endurance limitations: Answer: performance is limited by anaerobic
capacity (failure within a few moments)
Muscular endurance fatigue: Answer: is produced by accumulation of lactic
acid
Benefits of muscular fitness- resistive training: Answer: 1. increase thickness +
strength of the tissues
2. increase resistance to tear
3. improve body composition( % fat)
4. improve of flexibility
5. improvement of sport skills
6. increase joints stability
